Objective: To analyze immediate and midterm results of percutaneous mitral valvotomy (PMV) in
patients ≤ 18 year, a single centre experience of Sohag university hospital. Methods: Between May
2010 and May 2012, 64 procedures of Inoue technique mitral valvotomy were performed on 64
patients. The mean age was 15.8 ± 2.2 years; 75% were females. Results: Success was obtained in
96.8% of patients. Immediate complications were severe mitral regurgitation (3.1%), cardiac
tamponade (1.6%) and embolic stroke in (1.6%). Late follow-up was obtained in 93.7% of the patients
(at 6 and 24 months). Restenosis developed in 3 patients. Most of the patients had no symptoms
at discharge but most of them had NYHA class I to II at 6 months to 2 years follow up. No patients
died. Patients who operated early with MVA around 1.4 had best outcome. Conclusion: PMV
represents a safe therapeutic option in young patients with mitral valve stenosis. In these patients,
recurrence of symptoms and restenosis occurs at an earlier stage than in elderly. Earlier intervention
carries better outcome and decreases restenosis rate.
